SX4

Hi Corina. Thanks for contacting us today. Unfortunately, we really can't help you with this question, as we don't offer technical assistance on aftermarket systems. You should probably reach out to the manufacturer of the aftermarket system you want to...

Something like this is usually caused by a faulty headlight switch or a shorted wire going to the headlights. The source of the problem needs to be inspected so I would recommend having this looked at by a mechanic so...

Duralast Battery Cable, part number 07765 or part number 07764 will work on your vehicle. If you are seeking the negative terminal cable assembly, that is readily available from Suzuki dealers and easily installed. The positive side of the circuit...

Hello - your symptoms suggest a worn front wheel bearing (https://www.yourmechanic.com/article/is-it-safe-to-drive-with-a-wheel-bearing-gone). The "steering is a bit loose" symptom reinforces this diagnosis. If the noise ceases when turn left, it is likely the left wheel bearing. It would be the right...

Hello. Depending on how hard the starting was would help me to determine what is going on. If the engine just had a hard time cranking then it may be a problem with the battery or the starter. It may...

The computer in this car controls if the starter turns or not. You will need to have the computer scanned to see if the alarm is active. Have the batteries changed in the remote key FOB to see if this...

Hi there - "boundary measured engine temperature," or the lowest temp reading a sensor can transmit, can be different based on each temperature sensor. The issue here is what is the true engine temperature? Is the thermostat getting the engine...

Hi. I think the best thing to do with this situation is to replace the motor and get the proper radiator for the car. If the ECM has a fault or has gone bad completely the ECM will need to...

Thanks for writing in about your 2012 Suzuki SX4. The blower motor must of got water in it and has caused it to have a short internally. If you locate the blower and have it turned on but it doesn't...

The code P0139 (https://www.yourmechanic.com/article/p0139-obd-ii-trouble-code-o2-sensor-circuit-slow-response-bank-1-sensor-2) is for the O2 sensor (https://www.yourmechanic.com/services/oxygen-sensor-replacement) before the catalyst. The code is for when the engine control module is testing the O2 sensor it cuts the fuel to see if the O2 sensor detects a lean...

You may have more than a transmission filter problem. You should have a transmission mechanic like one from YourMechanic come and check the vehicle for the problem and isolate the causes of the loss of vehicle speed. It may be...

Both codes refer to the oxygen sensor that is to the rear of the catalytic converter. With regard to Code P0037 (https://www.yourmechanic.com/article/p0037-obd-ii-trouble-code-ho2s-heater-control-circuit-low-bank-1-sensor-2-by-john-nelson), if the rear oxygen sensor is brand new, you should check the heater circuit ground (the oxygen sensor...

Charging system output should be verified against factory specifications as the alternator may be failing or have failed thus accounting for the battery light. It is also possible that the serpentine belt does not have adequate tension and thus is...

Hi there. Are there any warning lights on? This would be a good starting point as the ECM will set codes to aid in the direction of diagnosis. Has a compression test been performed? A cylinder leakage test? What were...

Hello. In most cases the AC system should not affect the operation of the engine. If the issues only began after the AC was installed, it may be possible that the issue developed while the AC was being worked on....

Both of these sensors have to do with sending air mass and pressure information to the engine computer. It is likely you have a vacuum leak or these sensors are starting to fail and are offering the engine computer false...

The manufacture should be able to tell you. To my knowledge the US Department of Transportation will have that information available to you. You should be able to access that information on their website dedicated to making the roads safer:...

It would be recommended to replace the serpentine belts (https://www.yourmechanic.com/services/serpentine-drive-belt-replacement), water pump (https://www.yourmechanic.com/services/water-pump-replacement), and timing belt tensioner pulley with the timing belt (https://www.yourmechanic.com/services/timing-belt-replacement). You might even consider replacing the valve cover gasket (https://www.yourmechanic.com/article/how-long-does-a-valve-cover-gasket-last). If would like to have these repairs...

No, it is not the catalyst. The P0139 code (https://www.yourmechanic.com/article/p0139-obd-ii-trouble-code-o2-sensor-circuit-slow-response-bank-1-sensor-2) is for the O2 sensor before the catalyst. The code is illuminated when the engine control module is testing the O2 sensor and it cuts the fuel to see if...

Bad connection can be confusing. They are touching and the connection may even be tight, but electricity doesn't care about what our eyes see. Electricity happens at the atomic level. A bad connection is a loose connection or a surface...
